[Gluster-devel] 1.4.0 and HA Translator

[Melvin Wong]

Hi Krishna,
I am trying to add HA translator to my client config. But I get:

2008-12-26 19:08:57 W [write-behind.c:1363:init] writeback:
aggregate-size is not zero, disabling flush-behind
2008-12-26 19:08:57 W [write-behind.c:1363:init] writeback2:
aggregate-size is not zero, disabling flush-behind
2008-12-26 19:08:58 E [ha.c:4301:notify] glusterfs-ha: GF_EVENT_CHILD_UP
from io-cache
2008-12-26 19:08:58 E [ha.c:4310:notify] glusterfs-ha: switching
"active" from -1 to io-cache
2008-12-26 19:08:58 E [ha.c:4301:notify] glusterfs-ha: GF_EVENT_CHILD_UP
from io-cache2

Could you see what is wrong with my config? Thank you.
